You cannot compare a mod like this one to those "little" mods. (No offense) to those. Its just that ours is 2 -3 times larger, so there is no comparing. . . .
That was basically my point. Even so, my version of ROM is 2.37GB in size*, and it has no problems...Plus it doesn't explain why SVN3564 works fine EVERY time, and 3844 (or3853 from this morning) works ~50% of the time. Something got changed.
*and I have 64 mods taking up 23.5Gb, so the average size is 360+MB each
EDIT---that doesn't include C2C, as I deleted that mod for the time being this morning after my "test" from the BTS folder, as I don't want to play SVN3564, but it takes too long to get any other version to finally load correctly and by the time I do get it to load I'm no longer in the mood to play. If it is the large FPKs that are the problem, then splitting them up (or putting the assets back into the other folders) saves far more time than is gained by trying to load them and failing, and trying again and again and again...
